Ms. Adam’s is a new 3rd grade teacher. On the first day of class, after she introduced herself, she took out a large poster that read “Rules” at the top, with 20 bulleted “rules” below it. All rules began with “Do not…”. Ms. Adam’s then read over all 20 rules. By rule 10, 50% of her students lost interest and were not paying attention (i.e. looking out the window, doodling, opening and closing books on their desks, etc.). By rule 15, 90% of the class lost interest. When Ms. Adam’s finished reading all 20 rules, she noticed that some students were already breaking a few rules, many would not make eye contact with her and most ignored her when she quickly transitioned the students to the next activity- math (which had nothing to do with the rules).

use the sample information X =36, 0=7,n=20 to calculate the following confidence interval for u assuming the sample is from a normal population
Answers
The 90 percent confidence interval for the population mean (μ) is (33.423, 38.577).
How to calculate the valueConfidence Interval = X ± Z * (s/√n)
Where:
s is the sample standard deviation.
Given:
X = 36
s = 7
n = 20
For a 90 percent confidence level, the Z-score is 1.645 (corresponding to the 0.05/2 critical values from the standard normal distribution table).
Plugging in the values:
Confidence Interval = 36 ± 1.645 * (7/√20)
Confidence Interval = 36 ± 1.645 * (7/√20)
= 36 ± 1.645 * (7/4.472)
= 36 ± 1.645 * 1.567

what is the vertex of x^2 + 4x - 12
Answers
Answer:
\((-2, -16)\\\)
Explanation:
The vertex of a quadratic function which gets plotted as a parabola is either the minimum or maximum (x, y) value of that function.
The following rule applies to finding the x value of the vertex
\(\mathrm{The\:vertex\:of\:an\:up-down\:facing\:parabola\:of\:the\:form}\:\\y=ax^2+bx+c\:\mathrm{is}\:x_v=-\dfrac{b}{2a}\)
The equation is
\(y=x^2+4x-12\)
\(\textrm {Here }\\a = 1, b = 4, c= -12\\\\\)
\(So\; x_v, \textrm{ the x value of the vertex } = -\dfrac{4}{2\cdot \:1} = -2\\\\\textrm {Plug this value of x into the equation to find the y-value of the vertex}\\\)
\(y_v=\left(-2\right)^2+4\left(-2\right)-12\\\\\\y_v = 4 -8 - 12 = -16\\\\\)
\(\mathrm{Therefore\:the\:parabola\:vertex\:is}\\(-2, -16)\)
A three-year CD can be purchased at a bank for $3000 with an APR of 5.53% that is compounded quarterly. So that you can compare this opportunity to a CD available at some other bank, calculate the APY. (Round your answer to the nearest hundredth of a percent.)
Answers
Answer: 5.65%
Explanation:
Based on the information given, the annual percentage yield(APY) will be calculated as:
APY = (1+APR/Compounding periods)^Compounding periods - 1
= (1+5.53%/4)⁴ - 1
= (1 + 0.0553/4)⁴ - 1
= (1 + 0.013825)⁴ - 1

Answers
Answer: The mean marks of the remaining 100 students is 6000/100= 60.
Explanation: The mean marks of all the students is 45, and the mean marks of the top 100 students is 70, so the sum of the marks of the top 100 students is 70100=7000.
The mean marks of the last 100 students is 20, so the sum of the marks of the last 100 students is 20100=2000.
The sum of the marks of all the 300 students is 7000+2000+45*100=15000.
The sum of the marks of the remaining 100 students is 15000-7000-2000=6000.
The mean marks of the remaining 100 students is 6000/100= 60.

2. In its first year, “DM Trading” had the following experience: Unit selling price birr 100 Sales 50,000 units Total fixed cost birr 400,000 TVC birr 3,000,000 Required: a) Develop TR, TC and profit functions for the company in terms of quantity b) Find the breakeven point in terms of quantity and sales volume.
Answers
a) The total revenue (TR) function can be calculated by multiplying the unit selling price by the quantity sold.
In this case, TR = 100 * Q, where Q represents the quantity sold. The total cost (TC) function consists of the sum of fixed costs (FC) and total variable costs (TVC). Given that the fixed costs are 400,000 birr and the TVC is 3,000,000 birr, the TC function can be expressed as:TC = FC + TVC = 400,000 + 3,000,000 = 3,400,000 birr.
The profit function (P) can be determined by subtracting the total cost from the total revenue, so P = TR - TC = 100Q - 3,400,000 birr.
b) The breakeven point can be found by setting the profit function equal to zero, as this is the point where total revenue equals total cost.
In this case, 100Q - 3,400,000 = 0. Solving for Q, we find Q = 3,400,000 / 100 = 34,000 units. Therefore, the breakeven point in terms of quantity is 34,000 units. To calculate the sales volume at the breakeven point, we can multiply the breakeven quantity by the unit selling price:Sales Volume = 34,000 units * 100 birr/unit = 3,400,000 birr. Hence, the breakeven point in terms of sales volume is 3,400,000 birr.

Suppose that in North America, 23 % of people have type O blood. Suppose you have a sample of 2518 people. Compute the following: What is the mean number of people with type O blood (to 2 decimal places)? What is the standard deviation of the number of people with type O blood (to 2 decimal places)? Use a normal approximation to find the probability that in your sample there are less than 598 people with type O blood. Conditions: np = ≥ 10 n(1-p) = ≥ 10 Compute z-score (to two decimal places) z = Find probability (as a decimal) correct to four decimal places P(x < 598)
Answers
Note that the probability that in our sample of 2518 people there are less than 598 people with type O blood is approximately 0.8508.
What is the rationale for the above response?To find the mean number of people with type O blood in a sample of 2518 people, we multiply the sample size by the proportion of people with type O blood:
mean = 2518 x 0.23 = 578.14 (rounded to 2 decimal places)
To find the standard deviation of the number of people with type O blood, we can use the formula for the standard deviation of a binomial distribution:
standard deviation = sqrt(np(1-p)) = sqrt(2518 x 0.23 x 0.77) = 19.19 (rounded to 2 decimal places)
To use the normal approximation to find the probability that in our sample there are less than 598 people with type O blood, we need to standardize the value using the mean and standard deviation:
z = (598 - 578.14) / 19.19 = 1.04 (rounded to 2 decimal places)
Using a standard normal table or calculator, we can find the probability that z is less than 1.04:
P(z < 1.04) = 0.8508 (rounded to 4 decimal places)
Therefore, the probability that in our sample of 2518 people there are less than 598 people with type O blood is approximately 0.8508.

There are five (5) urns and they are numbered 1-5, each urn contains 10 balls. Uni has i defective and 10-i non-defective balls (i = 1, 5). An urn is chosen at random and then a ball is drawn from the chosen urn, the experiment does not know which of the urns was selected (i) What is the probability that a defective ball is drawn (ii) If the ball drawn turns out to be defective, what is the probability that it comes from urn i=5
Answers
Answer:
Explanation:
(i) The probability that a defective ball is drawn is equal to the total number of defective balls divided by the total number of balls. In this case, there are a total of 5 defective balls (one in each urn) and a total of 50 balls (10 in each urn), so the probability of drawing a defective ball is 5/50 = 1/10.
(ii) If the ball drawn turns out to be defective, the probability that it comes from urn i=5 is equal to the number of defective balls in urn 5 divided by the total number of defective balls. In this case, there is only 1 defective ball in urn 5 and a total of 5 defective balls, so the probability that a defective ball drawn comes from urn 5 is 1/5.

Explanation:
In a publishing company that prints products of varying dimensions, workers manually cut paper rolls into the required sizes. The company's management wants to install a computer-controlled system to do this task. If the system is installed, the employees would only need to enter the required paper dimensions into a computer, and a machine would cut the paper. How would the computer-controlled system be better than the manual system used by the publishing company?
Answers
1. Precision and Accuracy: A computer-controlled system can ensure precise and accurate cuts every time. It can be programmed to cut the paper rolls to the exact dimensions entered by the employees, eliminating human errors that may occur during manual cutting. This precision can enhance the overall quality of the printed products.
2. Increased Efficiency: Automating the cutting process can significantly improve efficiency. The computer-controlled system can work continuously without getting fatigued or requiring breaks, leading to faster turnaround times. This increased speed can boost productivity and allow the publishing company to handle larger volumes of work within shorter timelines.
3. Consistency and Standardization: Manual cutting can lead to variations in the dimensions of the cut paper rolls due to human inconsistencies. With a computer-controlled system, the cutting process can be standardized, ensuring consistent sizes for all products. This uniformity is crucial, especially in industries where precise measurements are essential for proper functioning or aesthetic appeal.
4. Waste Reduction: Human errors in manual cutting can result in paper wastage due to incorrect cuts. By using a computer-controlled system, waste can be minimized since the machine can optimize the cutting patterns and utilize the paper rolls more efficiently. This can lead to cost savings for the publishing company by reducing material waste.
5. Safety and Risk Reduction: Manual cutting can pose safety risks for workers, such as injuries from sharp cutting tools. With a computer-controlled system, the risk of accidents can be significantly reduced as there is minimal direct interaction with sharp objects. This promotes a safer work environment and decreases the chances of workplace injuries.
6. Flexibility and Adaptability: A computer-controlled system can handle a wide range of paper dimensions and sizes. Employees can simply enter the required dimensions into the computer, and the machine can quickly adjust and cut the paper accordingly. This flexibility allows the publishing company to cater to diverse customer needs and produce products with different specifications efficiently.
7. Data Collection and Analysis: By using a computer-controlled system, the publishing company can gather data on the cutting process, such as the number of paper rolls cut, the time taken, and any errors encountered. This data can be analyzed to identify areas for further improvement, optimize resource allocation, and make informed decisions regarding production planning and scheduling.
Overall, implementing a computer-controlled system for cutting paper rolls in the publishing company can bring about improved accuracy, efficiency, consistency, safety, and cost-effectiveness. It enables the company to enhance its productivity, meet customer requirements more precisely, and streamline the overall production process.
Answer:
The computer-controlled system would likely be better than the manual system used by the publishing company in several ways:
Precision: The computer-controlled system would be more precise and accurate than manual cutting. It can measure and cut the paper rolls with greater accuracy, reducing the likelihood of errors or waste.
Efficiency: The computer-controlled system can cut the paper rolls faster and more efficiently than manual cutting. This would increase the productivity of the workers and enable the company to produce more products in less time.
Consistency: The computer-controlled system would ensure consistent quality of the cut paper rolls. This is because the machine is programmed to cut the paper in the exact same way every time, which means that there is less room for human error or variation.
Safety: The computer-controlled system would be safer for the workers than manual cutting. It reduces the risk of injury from accidents or repetitive strain injuries associated with manual cutting.
Overall, the computer-controlled system would provide significant benefits for the publishing company in terms of precision, efficiency, consistency, and safety.

The class with the greatest frequency is the class "15.2 - 19" with a frequency of 7. The class with the least frequency is the class "0 - 3.8" with a frequency of 2.
To construct a frequency distribution with 5 classes for the given data representing time spent reading a political blog in a day, we need to determine the class intervals and calculate the frequency, midpoint, relative frequency, and cumulative frequency.
First, we find the range of the data:
Range = Maximum value - Minimum value
Range = 19 - 0
Range = 19
To determine the class width, we divide the range by the desired number of classes:
Class width = Range / Number of classes
Class width = 19 / 5
Class width ≈ 3.8
Now, we can construct the frequency distribution table:
Class Frequency Midpoint R. Frequency C. Frequency
0 - 3.8 2 1.9 2/20 = 0.1 2
3.8 - 7.6 4 5.7 4/20 = 0.2 6
7.6 - 11.4 4 9.5 4/20 = 0.2 10
11.4 - 15.2 3 13.3 3/20 = 0.15 13
15.2 - 19 7 17.1 7/20 = 0.35 20
By organizing the data into classes and analyzing the frequencies, we can gain insights into the distribution of reading time and identify the most and least common time intervals spent on reading the political blog.

Answers
The probability of a puppy having no spots in the next litter is 5/9 or 0.5556.
What is the explanation for the above response?To determine the probability of a puppy having no spots in the next litter, we need to find the proportion of previous puppies that had no spots. From the table, we can see that there were a total of 27 puppies (7 + 9 + 6 + 5) in the three litters, and 6 of them were black and white, and 9 were red and white, so:
The proportion of black and white puppies = 6 / 27 = 0.2222...
The proportion of red and white puppies = 9 / 27 = 0.3333...
Since none of the black and white or red and white puppies had spots, the proportion of puppies with no spots is:
Proportion of puppies with no spots = Proportion of black and white puppies + Proportion of red and white puppies = 0.2222... + 0.3333... = 0.5555.
So the probability of a puppy having no spots in the next litter is approximately 0.5555..., which can be rounded to 0.5556 or expressed as a fraction of 5/9. Therefore, the probability of a puppy having no spots in the next litter is 5/9 or 0.5556.
